Problems solved by technology

[0004] 1. The fixing effect of the installation method is poor. Only two points of the optical CT are connected to the bracket, and other parts are not supported. After a long time, it is easy to cause the optical cable to be deformed by gravity and cause damage.
[0005] 2. The repeatability of the installation project is poor, and the installation quality is not controlled during batch installation
[0006] 3. The optical CT is not protected, and the optical cable is only protected by the outer layer. In the harsh external environment, the outer layer is easy to deteriorate and eventually cause damage to the optical CT.

Embodiment 1

[0025] Such as Figure 1-2 As shown, a GIS optical current transformer installation device is used to install the cable 1 and the optical cable 2 at the same time. The device includes a cable installation bracket, an optical cable storage box, and an optical cable locking joint. The cable 1 is fixed on the cable installation bracket. The optical cable storage box is fixed on the cable 1, and the optical cable 2 is coiled in the optical cable storage box and led out through the optical cable locking joint.

[0026] The optical cable storage box includes a storage box 3 for storing optical cables and a clamp 4 and a bracket 5 for fixing the storage box. The storage box includes a coil-shaped box body, a box cover that matches the box body, and the box body The cross-section of the box is "I", the box body is set on the cable, the optical cable is coiled on the side of the box body, the box cover is set on the side of the box body, and the storage box 3 is fixed on the clamp 4 th...

Embodiment 2

[0030] The storage box 3 is in the shape of a square box, and one side of the storage box 3 is fixedly connected to the hoop 4 through a bracket, and the hoop is fixed on the cable 1 . All the other are with embodiment 1.

Abstract

The invention relates a GIS (gas insulated substation) optical current transformer installing device which is used for installing an electrical cable and an optical cable at the same time. The GIS optical current transformer installing device comprises an electrical cable installing support, an optical cable accommodating box and an optical cable locking connector, wherein the electrical cable is fixed on the electrical cable installing support; the optical cable accommodating box is fixed on the electrical cable; and the optical cable is coiled inside the optical cable accommodating box and is led out through the optical cable locking connector. Compared with the prior art, the GIS optical current transformer installing device has the advantages of high stability, good repeatability and the like.

Description

technical field [0001] The invention relates to the installation of an optical current transformer, in particular to a GIS (Gas Insulated Substation) optical current transformer installation device. Background technique [0002] The all-optical current transformer has the characteristics of small size and flexible installation, and its installation is different from the traditional electromagnetic transformer. When installing in combination with GIS, in order to solve the problem of connecting the all-optical current transformer with the GIS combined electrical appliance, solve the related insulation and sealing problems, and consider the advantages of the small size of the all-optical current transformer, it is necessary to design a different from the traditional one. How to connect and install transformers. [0003] Now it is generally used to install the flexible all-fiber optic current transformer (optical CT) under the indoor cable barrel, and the exposed space surroun...
